The initial work was commissioned in 1995 by La Muse en Circuit. We performed it in the spring of that year in the studios of this group in Alfortville (Paris).

We dealt with the problem of immigration in Europe. It is a radio artwork that is sometimes very close to the documentary genre, which includes interviews with immigrants and political refugees in various reception centres and associations in Madrid, as well as with various heads of centres and embassies in Madrid and Paris.
The train is here a metaphor, in the etymological sense of the term: a means of transport. The train, that "iron horse", as the American Indians called it, is in this case a central character loaded with hopes and omens, songs and tears. How many of those who came to cross the threshold into the so-called First World found the Paradise they dreamed of? In the twenty-first century, these problems, these personal tragedies, have multiplied, and the possible solutions have been postponed or diluted, aggravated by the misgivings, xenophobia and short-sightedness that our societies have displayed in this regard. Unfortunately, therefore, we are dealing with a subject that is strictly current, despite the time that has elapsed.

The work, in two of its versions, has been part of two historical events of sound art that enjoyed wide international resonance. Thus, the initial work was premiered on Horizontal Radio, an event organized by the Ars Acustica group of the EBU (European Broadcasting Union), during 24 hours between June 22 and 23, 1995. The general concept that encouraged the participation of radio stations and sound artists from twenty cities in three continents was Migrations, which coincided fully with the theme of our work.
A year later, a similar event took place, entitled
Rivers & Bridges, and as part of the Spanish participation in this event we produced, using materials from that initial work and some of our own texts, four short capsules entitled Interference Pieces. That same year we incorporated those pieces into the 1995 work, and this is the definitive version presented here.

The diagrams and notes on montage, editing and mixing that we show below belong to sessions that took place in the studios of La Muse en Circuit in 1995.
